How does dining surround chair with armrest improve improved posture?

Dining surround chairs with armrest can contribute to improved posture in the following ways:
Upper Body Support: Armrests provide a place for diners to rest their forearms and hands. This encourages a more upright sitting position by preventing the shoulders from hunching forward and promoting a natural alignment of the spine.
Spinal Alignment: When using armrests, individuals are more likely to sit back in the chair, which helps maintain the natural curvature of the spine. This alignment reduces the risk of slouching or leaning forward, both of which can lead to poor posture and discomfort.
Reduced Strain on Neck and Shoulders: Without armrests, diners might inadvertently strain their necks and shoulders by leaning forward or holding their arms awkwardly while eating. Armrests alleviate this strain by providing a comfortable support surface for the arms.
Engagement of Core Muscles: Using armrests can encourage the engagement of core muscles as diners sit upright. The support provided by the armrests allows individuals to use their abdominal and back muscles to maintain balance and stability.

Less Pressure on Lower Back: Armrests encourage a more relaxed and balanced sitting position, which in turn reduces the pressure on the lower back. This can be especially beneficial for individuals who are prone to lower back discomfort.
Prevention of Forward Head Posture: Forward head posture, where the head extends too far forward from the body's center of gravity, can be discouraged with the use of armrests. Proper alignment of the arms and shoulders helps keep the head and neck in a neutral position.
Encouragement of Full Backrest Utilization: With armrests, diners are more likely to use the entire backrest of the chair. This provides better overall support for the spine and helps distribute body weight more evenly.
Stable Sitting Base: Armrests provide additional points of contact with the chair, creating a stable sitting base. This stability encourages better posture as individuals are less likely to shift and fidget to find a comfortable position.
Awareness of Body Position: Armrests serve as a tactile reminder for diners to maintain proper posture. They provide a boundary that encourages individuals to stay within the boundaries of the chair and sit back comfortably.
Comfortable and Relaxed Seating: When individuals are comfortable and well-supported by armrests, they are less likely to adopt awkward positions that compromise their posture. This contributes to a more natural and relaxed sitting experience.
